Optimising Healthcare Education with Design-Based Theory

Introduction In complex, and socially dynamic educational systems, traditional research methodologies often fail to connect with everyday practice, creating a need for “usable knowledge” when solving individual and collective education problems (Design-Based Research Collective, 2003). Traditional methods are effective, but do not necessarily uncover the nature of changes to student thinking during an education experience. With this, Design-Based Research (DBR) is a proposed solution that emerges as a pivotal methodology in educational research, as it aims to integrate theories of learning with practical experiences. Seen as a systematic yet adaptable approach, DBR integrates iterative cycles of analysis, design, and evaluation in collaboration with researchers and practitioners within authentic educational settings, (Harrington, 2012; Wang & Hannafin, 2005). This (poster) presentation will describe how DBR was utilised to create a learning environment to improve learning experiences within healthcare education. An analysis of the problem highlighted that healthcare students experienced high levels of anxiety during high-fidelity simulation when asked to perform and treat simulation manikins (Aiello et al., 2023). In part, the main issues relate to a lack of environmental authenticity, resulting in under-stimulation and performance anxiety resulting in over-stimulation. This relates to the Yerkes Dodson stress performance curve and suggests that too little or too much arousal results in poor performance (Yerkes, 1908). The hypothesis therefore was to design a solution for peak performance by increasing environmental authenticity and managing anxiety. Method The hypothesis is conceptualised as a ‘design solution’ rather than an intervention. To provide an authentic learning experience virtual reality environments were developed, and to aid performance anxiety, the centering technique was used. Centering is a visualisation technique that teaches participants to focus on the here and now, reduce negative thoughts, and lower anxiety. Virtual reality scenarios were provided prior to each simulation and included a ward-based environment (nurse students) and a rescue helicopter (paramedic students). The study involved 35 Master of Nursing Science, Entry to Practice student nurses at the University of Melbourne and 33 Bachelor of Health Science, Paramedicine students at Auckland University of Technology and industry experts within nurse and paramedic education. All data was collected for each cohort iteratively in 2023 and 2024 to evaluate and develop the design. Data collection included using the State-Trait Anxiety Inventory as a pre-test baseline to measure general and long-standing anxiety for each participant. Within-test heart rates was recorded on a Polar H10 chest strap to measure an objective physiological response to stress. Post-test participants completed the Competitive State Anxiety Inventory–2R after each simulation to understand subjective anxiety and several focus groups were completed to gain further insight into experiences and perspectives. Discussion and Conclusion This presentation outlines the design characteristics used to support student learning within healthcare education settings. Design-Based Research offers a robust framework to develop and refine educational practices through iterative design and implementation cycles. Early results suggest that both virtual reality and the centering technique impact healthcare learning and the implementation of this approach could lead to long-term resilience and build confidence that maximises potential.

A low‐cost trans‐scale model for the collaborative analysis of the manufacturing and in‐service process of unidirectional CFRP composites

AbstractDuring the manufacturing of thermoset‐based carbon fiber‐reinforced polymer (CFRP) structures, a curing process involving thermal, chemical, and mechanical interactions occurs. This process gives rise to micro‐scale residual stresses due to differences in fiber and resin properties, leading to decreased mechanical properties compared to nominal values. A trans‐scale analysis method utilizing the reduced order model (ROM) is applied in this study to establish a connection between the manufacturing and in‐service processes for unidirectional CFRP (UD‐CFRP). By employing this method, the evolution of residual stresses at the micro‐scale during UD‐CFRP manufacturing is predicted, and the impact of these residual stresses on structural performance during service is assessed. Specifically, the manufacturing‐induced residual stresses reduce the material strength by a minimum of 19.31%, while also exploring the correlation between macro‐scale and micro‐scale failures. Notably, the computational cost of this method is significantly lower, with a reduction factor of 103 compared to the finite element method. Empirical evidence supports the effectiveness of this method in accurately predicting outcomes throughout both the manufacturing and in‐service processes.Highlights Trans‐scale analysis method links composites manufacturing simulation to in‐service performance. Highly efficient trans‐scale method excels in cost, accuracy, consistency, and convergence. Residual stresses from the curing process significantly impact matrix safety.

A Bibliometric Review of Indoor Environment Quality Research and Its Effects on Occupant Productivity (2011–2023)

Over the past decade, there has been a growing recognition of the importance of indoor environmental quality (IEQ) in influencing occupant productivity. Researchers have studied various buildings, including offices, schools, hospitals, and residential settings, to understand the relationship between IEQ and productivity outcomes. Studies have taken a multifactorial approach, considering multiple aspects of IEQ. Evidence from the literature review suggests that the quality of the indoor environment is an essential factor that affects the productivity of building occupants, and it is one of the fundamental issues in the development of societies. This area of research requires the responsible participation of researchers at all levels, as there is significant scope to contribute to knowledge. Therefore, this study aims to conduct a bibliometric analysis of the published literature on indoor environmental quality and its impact on building occupant productivity through the scientific literature available from one of the largest and most famous academic databases, Scopus; the study was determined in 2011 to 2023. The search used differential thresholds for IEQ keywords affecting building occupant productivity. Three discrete queries were performed, resulting in approximately 3861 publications. These were filtered by reducing false positives and excluding publications irrelevant to the research topic. The final results were 72 publications. This study also used Excel and VOS viewer to analyse and create graphs and network visualisation maps to show the growth of publications and their types, active countries and institutions for recovered publications, international collaboration, author keywords, active journals, and citation analysis. This study can significantly advance our understanding of building occupant productivity and enhance quality of life and work. Evaluating the research outputs is essential for highlighting contributions to knowledge and global collaboration in this research area. The potential impact of this study is not just theoretical. It can shape the future of our built environments and the lives of those occupying them.

Leveraging Federated Learning for Privacy-Preserving Analysis of Multi-Institutional Electronic Health Records in Rare Disease Research

This research announces that the fresh federated learning structure is designed to enhance the privacy-preserving analysis of electronic health records (EHRs), and multiple institutions in this framework permit secure collaboration among institutions, allowing them to train machine-learning replicas without directly sharing patient data. We implemented and evaluated numerous machine-learning models to forecast patient treatment needs, including Logistic Regression, Decision-Tree-Classifiers, Support-Vectors-Classifiers, Random-Forests, and Stacking-Classifiers. The Random Forest classifier achieved the best performance with an accuracy of 90% and an F1 score of 80%, demonstrating that it handled complex and imbalanced datasets. This FL-based approach not only complies with privacy regulations such as HIPAA and GDPR but also overcomes significant challenges in data sharing, making it ideal for rare disease research. By enabling secure data aggregation across institutions, the framework significantly enhances the ability to study rare diseases and accelerates the discovery of new treatments. Future directions include extending this framework to other areas of healthcare and incorporating advanced machine-learning techniques to enhance its capabilities further. This research sets the new standard for secure and collaborative healthcare data analysis and promotes innovation and ethical practices in rare disease research.

Machine Learning on 50,000 Manuscripts Shows Increased Clinical Research by Academic Cardiac Surgeons

IntroductionAcademic cardiac surgeons are productive researchers and innovators. We sought to perform a comprehensive machine learning (ML)-based characterization of cardiac surgery research over the past 40 y to identify trends in research pursuits. MethodsUS-based academic websites were queried for surgeon profiles. Publications since 1980 were obtained from Web of Science, and publication classifications (e.g., “human”, “animal”) were collected through the National Institutes of Health iCite tool. Publications were deemed “basic or translational” if >50% of their classification was under “animal” or “molecular or cell”, and “clinical” if otherwise. ML-based clustering was performed on publication titles and Medical Subject Heading terms to identify research topics. ResultsA total of 944 cardiac surgeons accounted for 48,031 unique publications. Average citations per year have decreased since 1980 (P < 0.001). The percentage of basic or translational publications by cardiac surgeons has decreased over time (P < 0.001), comprising of only 8% of publications in 2022. Adult cardiac surgeons, those who received an F32, K08, or R01, and those with a PhD were more likely to publish basic or translational research. Top areas of basic or translational research were myocardial reperfusion, aortic aneurysms or remodeling, and transplant immunology. Major areas of clinical research included aortic disease, aortic valve disease, and mechanical circulatory support. Collaboration analysis revealed that 55% of publications were single-center, and the yearly percentage of these publications has decreased over time (P < 0.001). ConclusionsCardiac surgeons are performing less basic or translational research relative to clinical research than ever before. The majority of publications over the past 40 y did not involve cross-center collaboration. Continued support for clinical research is needed, while also encouraging collaborative basic or translational science to foster innovation in patient care.

Synthetic Data, Common Data Models and Federation: Holy Trinity or unholy mess?

The healthcare sector's adoption of data and digital technologies is hindered by stringent data privacy regulations. Synthetic data, common data models (CDMs) and federated data ecosystems present promising solutions to these challenges. This workshop explored the potential of synthetic data to revolutionise health research, education and innovation (REI). By discussing applications, benefits, and ethical implications, the workshop addressed the role of synthetic data in enhancing data interoperability, scalability, and privacy preservation within healthcare REI systems. It also examined the relationship between synthetic data and CDMs, such as the Observational Medical Outcomes Partnership (OMOP) CDM, and the potential of federated data ecosystems to enable collaborative analysis while maintaining data ownership and control. The workshop delved into specific use cases to assess the feasibility, benefits, and limitations of synthetic data in various healthcare contexts. Through case studies and discussions, participants explored and developed best practices for effective utilisation. Ultimately, the workshop aimed to explore whether the combination of synthetic data, CDMs, and federation could facilitate privacy-preserving data sharing, seamless data integration, and scalable analysis across distributed data sources. By addressing privacy, interoperability, and scalability challenges, these approaches can drive innovation and insights within the healthcare sector.

A lifestyle program for socially vulnerable community-dwelling elderly

Abstract Problem Socially vulnerable older adults often face lower health literacy and limited access to health care. Description of the problem Current lifestyle programs are often insufficiently adapted to this socially vulnerable target group. As a result, these older adults are underrepresented in lifestyle programs. From a public health perspective, lifestyle programs that improve the poorer physical and mental health of these older adults, should be made more accessible by involving the expertise, participation and needs of this group. The aim of this study was to develop and implement a lifestyle program adapted to the expectations and needs of socially vulnerable older adults. Results Both the target group and the local community (health) centers were involved during the co-creative phase of development. A neighborhood analysis was used to identify and reach out to the target group. Motivators and barriers for a healthy lifestyle were identified through focus groups. The developed program consisted of 10 weekly group sessions. Various health aspects were integrated, including exercise, nutrition, stress, sleep, positive psychology, meaningful living, and motivation. Nine centers for community dwelling older adults in Flanders and Brussels were included. In total, 93 older adults were recruited out of which 76 completed the full program. In the final phase, the program was evaluated by means of objective and subjective measuring methods. Finally, the local community (health) centers are currently involved in the program’s sustainability through a trainers’ program. Lessons The belongingness, the catering, the empowering attitude of the trainer and the ‘fun’ factor turned out to be success factors for the adherence to the program. The participating centres experienced an increase in numbers of older adults that were attracted to their activities that are focused on healthy lifestyle behaviors. The continuity of the program is currently being examined. Key messages • A neighbourhood analysis in collaboration with local partners helped to reach the target group. • The program was made attractive by the involvement of the older adults, the fun-factor and the small groups.

Claimant and clinician perspectives on sources of claimant distress in interactions with Australian compensation schemes: a qualitative study

Purpose Recovering from compensable injuries can be influenced by a variety of factors including the claimant’s experience of distress during the claims process. In order to develop cross-scheme, nation-wide strategies to improve claimants’ interactions with the compensation system, reduce claimant distress, and improve claimant outcomes, it is important to understand sources of claims-related distress from the perspective of both claimants and clinicians. Methods An exploratory qualitative design was undertaken using semi-structured interviews with 13 claimants and 26 clinicians from four injury compensation schemes in five Australian states. A collaborative and reflexive thematic analysis was undertaken with an inductive approach to coding, and themes were constructed for claimants and clinicians across compensation schemes. Results Claimants and clinicians interviews revealed four main sources of distress, including (1) complexity and delays in administrative processes, (2) interruptions to recovery caused by treatment delays, (3) non-individualised approaches to care, and (4) a lack of support for navigating the claims process. Conclusion Sources of claims-related distress identified by claimants and clinicians in the present study point to the urgent need for nationwide systems level changes to reduce claimant distress in the pursuit of better claimant outcomes.

Wonderful and Dangerous Entanglements Between Youth Culture, Contemporary Art and Present Pedagogics

The article aims to describe and discuss how a particular affinity can be identified between contemporary art, trends in children’s and young people’s culture, and present pedagogical approaches found in afterschool clubs, gymnasium and Social Education in a Danish context. Methodologically, inspiration is drawn from self-study research, involving several analytical sessions in which the authors of this article engaged in collaborative analysis of empirical cases chosen from their own practice. The selected cases are discussed through three thematic lenses: creativity, reflection, and time. Theoretically, the article refers to distributed aspects of creativity, the role of craftsmanship, and the apparent acceleration of society. The article concludes that pedagogical methods derived from contemporary art meet young people’s need for participation, inclusion, and influence but also contend with conditions in present society, such as limited time for immersion, a general acceleration of society, academization of our educational institutions, and a general downgrading of manual techniques.

Studio as a Catalyst for Incremental and Ambitious Teacher Learning

This article explores how the practice-focused Studio professional learning (PL) model can provide incremental and ambitious teacher learning opportunities. We argue that when the model’s structures and practices are grounded in ambitious and equitable teaching, they catalyze incremental teacher learning. Studio, like lesson study, supports teachers in considering the entailments of lessons, focusing on the live shared enactment to strengthen teaching and learning through collaborative analysis and reflection. To build our argument, we drew from two Studio projects that had shared structures of cycles of learning and routines, as well as shared practices of using rich representations and collective interpretations of teaching. While both projects’ structures and practices take up ambitious and equitable teaching, they use different routines and attend to different features of equitable teaching. Building on a history of PL models, such as lesson study, which use similar structures and practices as powerful catalysts of teacher learning, we argue that Studio’s structures and practices can catalyze teachers’ incremental learning of ambitious and equitable teaching. We discuss the implications for future research based on this argument and for those leading PL.

ChatGPT Affordances and Indonesian EFL Students’ Perceptions in L2 Writing: A Collaborative Reflexive Thematic Analysis

ABSTRACT This study explores ChatGPT affordances, students’ use of prompts, and their perceptions of using the tool in EFL writing. With screen capture technology to observe students’ interactions with ChatGPT during writing process and semi-structured interviews, the data were analysed using a collaborative reflective thematic analysis. The results revealed that students’ use of ChatGPT has the potential to improve their essay quality in terms of lexical resources, grammatical range and accuracy, and coherence and cohesion. ChatGPT also provides such affordances as brainstorming, essay outlining, idea development, and feedback on hedging devices. Overall, students considered ChatGPT a valuable personal learning tutor that may stimulate student autonomy by offering immediate feedback in a less anxiety-provoking learning environment. However, some experienced challenges in producing effective prompts and understanding ChatGPT’s feedback. The study concludes that while the use of ChatGPT can enhance L2 writing development, teachers’ guidance is necessary during students’ interaction with the tool.

Music and the politics of famine: everyday discourses and shame for suffering.

Understanding the politics of famine is crucial to understanding why famines still occur. A key part of this is how famine is remembered, understood, and discussed. This paper focuses on songs popular among communities that have recently experienced deadly famine. Contemporary famines almost always manifest in armed conflict contexts, where there is limited political freedom. Here, songs and music can be an important way to debate sensitive political issues. This paper focuses on the way that songs and music shape 'regimes of truth' around famine, and who is shamed and held accountable for associated suffering. It is based on long-term ethnographic research, the recordings of famine-related songs, and collaborative analysis in Jonglei and Warrap States (South Sudan) in 2021-24. The paper shows how songs can mock soldiers for their seizing of assets during times of hunger and how they can create familial shame for famine suffering, shifting responsibility away from the real causes to family members.

An effective approach to tackling complex health policy challenges. Using a clinical microsystems approach and rethinking codesign.

That people with serious mental illness have poor physical health and face a significant life expectancy gap compared with the general population is well known. Despite considerable policy focus in some countries, the gap in life expectancy remains. Tackling complex and persistent health problems such as this requires a systems-based approach, recognising the complexity of interacting components and their effects on the problem and on each other and applying collaborative analysis, design and implementation by those with knowledge of and expertise in the problem and the context. This paper describes the methods used to develop the Australian Being Equally Well National Policy Roadmap for better physical health care and longer lives for people with severe mental illness. Whilst recognising that high rates of physical health comorbidities are caused by many factors including lifestyle, access to high-quality healthcare and medication side effects, the work was focused on what could be done within Australian primary care to improve the physical health of this cohort. A Clinical Microsystem Approach was applied to synthesise clinical evidence with professional and lived experience, and an innovative policy development process was established, creating trust across all system levels. Participants with different kinds of knowledge and experience worked in discrete groups according to their professional or expert role whilst also being supported to participate in an intensive cross-collaboration. The potential value of this methodology for tackling other complex problems in health policy is discussed.

Exploration and creation of meaningful teacher educator practises in physical education teacher education

ABSTRACT This paper examines four teacher educators’ work practices which either perceive to enhance or diminish meaningfulness in physical education teacher education. Through a community of learners, we took a narrative inquiry approach and in particular, a storytelling approach (Chiu-Ching & Chan, 2009. Teaching and learning through narrative inquiry. In D. Tidwell, M. L. Heston, & L. M. Fitzgerald (Eds.), In Research Methods for the Self-Study of Practice. Springer), to exploring, identifying, and examining meaningful teacher education practices. Stories (and elicited stories) were collected through recorded zoom meetings, critical discussions, and note taking. Collaborative data analysis resulted in three categories: (i) Ownership of practice as key to meaningful teacher educator practices; (ii) The influential interdependent relationships on the potential of meaningful teacher educator practices; and (iii) The power of reflection in learning from, and designing, meaningful teacher educator practices. We share considerations for other teacher educators in how they can strive towards developing meaningful teacher education practice, for example, we encourage teacher educators to engage in individual and collective reflection by being vulnerable.

Damage behavior and toughening mechanism of SiCf/SiC-Ti3SiC2 composites: A combination of digital image correlation and acoustic emission

Matrix modification is an effective method to improve the mechanical properties of ceramic matrix composites, while the elucidation of corresponding damage mechanism is essential for the design and engineering application of composites. In this work, Ti3SiC2 particles were introduced into SiC matrix to fabricate Ti3SiC2 modified SiCf/SiC (SiCf/SiC-Ti3SiC2) composites by a hybrid technique of slurry suspension impregnation combined with polymer infiltration and pyrolysis. Compared with SiCf/SiC composites, the flexural strength and modulus of SiCf/SiC-Ti3SiC2 composites were increased by 17.8 % and 61.0 %, respectively. The three-point flexural damage behavior and failure mechanism of composites were systematically investigated and compared by the combination of digital image correlation and acoustic emission techniques. Based on the collaborative analysis of in-situ damage process, matrix micro-zone toughness and fracture morphology, the modification effect and toughening mechanism of Ti3SiC2 were revealed. The improved mechanical properties of SiCf/SiC-Ti3SiC2 composite could be ascribed to the more sufficient matrix cracking before composite failure and the increased matrix fracture energy by microcrack deflection. After matrix modification, the failure mechanism was dominated by the gradual propagation and growth of microcracks until the critical crack size, instead of the fast and unstable propagation of main crack.

Sewage Treatment Equipment Supply Chain Collaboration and Resilience Improvement Path Analysis: Collaborative Decision-Making, Information Sharing, Risk Management

Since the dawn of the 21st century, supply chains (SCs) have faced an array of unprecedented challenges, encompassing economic volatility, escalating geopolitical conflicts, intensified trade disputes, and persistent environmental degradation. These challenges have imposed immense pressures on SCs, amplifying both the risks and occurrences of disruptions. In response to these critical demands, there has been a substantial increase in academic, industrial, and governmental focus on the resilience and recovery capabilities of SCs. In this context, the supply chain (SC) for sewage treatment equipment has been significantly affected. This study aims to systematically investigate collaborative strategies and mechanisms for bolstering the resilience of manufacturing SCs within the sewage treatment sector, with particular attention to collaborative decision-making, information sharing, and risk mitigation throughout the SC lifecycle. Following a comparative analysis of various methodologies, this paper employed the structural equation model (SEM) and subsequently conducted a comprehensive survey of manufacturers specializing in glass fiber sewage treatment systems, yielding 385 valid responses. Through this data, a structural equation model was developed to analyze pathways for resilience enhancement. A thorough analysis of the results indicates that Supply Chain Collaboration (SCC) and collaborative decision-making are instrumental in strengthening Glass Fiber Sewage Treatment Supply Chain Resilience (SCR) through the implementation of effective information sharing and risk management practices. These findings contribute to the theoretical framework of SCC and SCR by clarifying the influence of collaborative practices while also providing practical guidance for the governance and strategic management of sewage treatment equipment enterprises and their associated SCs. The conclusions drawn from this study can guide us in establishing a more resilient and sustainable SC ecosystem, making it more directive and capable of mitigating complex disruptions.

Methodological Implications for Video-Based Research in the Library and Information Science

The use of video has been popular in psychology and educational research (Erickson, 2011), but still is relatively new to the Library and Information Science (LIS) field. Video technology is a powerful tool for documenting events, allowing them to be preserved permanently and viewed un unlimited number of times for collaborative data analysis (Jordan &amp; Henderson, 1995). In addition, it is important to consider that video recordings start with a choice of the recorder on which part to capture and follow with a deliberate and selective choice on which recordings to focus on analytically. Thus, researchers who choose to employ video-based research need to be reflexive of the affordances and limitations of using certain video technology and be cognizant of the ways in which we can be closer to capturing the phenomenon itself. In this poster, we will demonstrate two cases of family programming at public libraries where video-based research was used for research and explore the methodological implications of video-based research in LIS. We aim to discuss the opportunities and challenges of capturing in-situ data in addition to participants’ retrospective perspectives after their participation in library programming.
